On the 30th of August, 2006, at Caixaforum ( Barcelona ), Freesound organized a multitudinous (more than 300 people) performance and sound recording called "La audiencia disponible". This sound is one of those recorded that day. Among who made all this possible there is Ruben Grilo, Bram de jong and Jaume Ferrete, with Jose Lozano on sound and Mateo Vergara as crowd conductor and the help and support of Carmen Garrido director of La Mediateca at Fundació la Caixa. Applause, clapping with their hands.
